The outer surface of the external condyle presents, a little behind its centre, an eminence, the outer tuberosity (epico7idylus lateralis); it is less prominent than the inner tuberosity, and gives attachment to the external lateral ligaments of the knee. Immediately beneath it is the popliteal groove, which commences at a depression a little behind the centre of the lower border of this surface; the front part of this depression gives origin to the Popliteus muscle, the tendon of which is lodged in the groove during flexion of the knee. The groove is smooth, covered with hyaline cartilage in the recent state, and runs upward and back- ward to the posterior extremity of the condyle. The posterior extremity is con- vex and smooth; just above and to the outer side of the articular surface is a de- pression for the tendon of the outer head of the Gastrocnemius, above which is the origin of the Plantaris. The inner surface of the inner condyle presents a convex eminence, the inner tuberosity {epicondyliw medialis), rough, for the attachment of the internal lateral ligament. Just above the articular surface of this condyle, behind, is a depres- sion for the tendo
